Coal miners safety monitoring system

Abstract

Security and automation is a prime concern in our day to day life. In the last few years we can observe many such incidents where the workers in coal mines had lost their life due to the hazardous accidents in mining area. To avoid this problem we have developed a project ―Coal miners safety monitoring system‖. The system gives both audible and visual alerts using LCD and buzzer. The system also monitors the LPG gas leakages victimization gas detection device, fire using temperature sensor, in the mines and if it exceeds the brink level, it alerts through alarm victimization buzzer and conjointly displays on digital display to the user. The LDR sensor detects the light intensity and automatically controls the light using relay switch. This sensors output is given to the Arduino for further processing to send the monitored parameter value to the control station using Wi-Fi module. In this project we are also using GSM module to send alert message to the registered user about fire and gas leakages.
